復制代碼 代碼如下:

[注] 添加mysql組和用戶
#groupadd mysql
#useradd -g mysql mysql
[注] 解包到/usr/local
# tar -xzf mysql-standard-4.1.9-pc-linux-gnu-i686.tar.gz -C /usr/local
[注] 建立軟鏈接，方便操作（此處給此連接命名為mysql001，也可為其它的名字）
#cd /usr/local
#ln -s mysql-standard-5.0.15-linux-i686-glibc23 mysql001
#cd mysql001
#scripts/mysql_install_db
#chown -R root .
#chown -R mysql data
#chgrp -R mysql .
[注] 復制data，以供單版本多實例分配
#cp -a data data_1
#cp -a data data_2
[注] 添加多實例配置文件
#cd /usr/local/mysql001/bin
#cat >my_multi.cnf
[注] 以下是my_multi.cnf的配置信息，可依此復制
[mysqld_multi]
mysqld = /usr/local/mysql001/bin/mysqld_safe
mysqladmin = /usr/local/mysql001/bin/mysqladmin
user = root

[mysqld1]

[mysqld2]

datadir = /usr/local/mysql001/data_2

復制代碼 代碼如下:

#vi /etc/profile # 添加系統環境變量。
export MYSQL_HOME=/usr/local/mysql001/bin
export PATH=$PATH:$MYSQL_HOME

復制代碼 代碼如下:

vi /etc/rc.local
# 添加
mysqld_multi --defaults-extra-file=/usr/local/src/mysql_dir/bin/my_multi.cnf start 1,2
